A friend of mine wanted to lock all of the public entries of her LJ, but not having a paid account, she couldn't use the built-in tools. As a result, I wrote a tool that will friend lock all public entries in a Livejournal (or, with a small bit of work, any other journal supporting the LJ API), but not touch any private or existing friend-locked posts. There's no GUI for it, and it takes the username and password from the controlling terminal.
Requires Python.
